在工程应用中需要通过连接不同的材料制成零部件以满足不同的要求。由于所用材料的力学、热和电性能存在巨大差异,使得这些零部件的制造极具挑战性。搅拌摩擦焊(FSW)能够用于连接异种材料,如铝(Al)和铜(Cu)。关于异种材料的连接,特别是铝-铜,文献来源比较分散,因此,铝-铜搅拌摩擦焊的信息收集比较繁琐。本文综述铝-铜的搅拌摩擦焊,为科研人员提供相关信息。文中全面涵盖和系统总结铝-铜搅拌摩擦焊的各项问题,如工具设计和尺寸、工艺参数以及流程对零件力学性能、微观组织和缺陷形成的影响。此外,还提出和探讨铝-铜搅拌摩擦焊的几个改进工艺。该工作不仅列举前人的主要成果,还提出铝-铜搅拌摩擦焊的发展建议。
In engineering applications, it is necessary to make parts by connecting different materials to meet different requirements. Due to the vastly different mechanical, thermal and electrical properties of the materials used, the manufacture of these components is extremely challenging. Friction stir welding (FSW) can be used to join dissimilar materials such as aluminum (Al) and copper (Cu). As for the connection of dissimilar materials, especially aluminum-copper, the sources of literature are relatively scattered, therefore, the information collection of aluminum-copper friction stir welding is complicated. This review summarizes the friction stir welding of aluminum-copper and provides researchers with relevant information. The paper comprehensively covers and systematically summarizes the problems of aluminum-copper friction stir welding, such as tool design and size, process parameters and the influence of the process on the mechanical properties, microstructure and defect formation of parts. In addition, several improvements of aluminum-copper friction stir welding are also proposed and discussed. This work not only cites the main achievements of predecessors, but also proposes the development suggestions of aluminum-copper friction stir welding.
